    Abstract: A method and apparatus is disclosed for an electron beam directed energy device. The device consists of an electron gun with one or more electron beams. The device includes one or more accelerating plates with holes aligned for beam passage. The plates may be flat or preferably shaped to direct each electron beam to exit the electron gun at a predetermined orientation. In one preferred application, the device is located in outer space with individual beams that are directed to focus at a distant target to be used to impact and destroy missiles. The aimings of the separate beams are designed to overcome Coulomb repulsion. A method is also presented for directing the beams to a target considering the variable terrestrial magnetic field. In another preferred application, the electron beam is directed into the ground to produce a subsurface x-ray source to locate and/or destroy buried or otherwise hidden objects including explosive devices.

    Abstract: An object of the present invention is to suppress measurement errors caused by the fact that the shrink amount due to scan of an electron beam differs pattern by pattern. To accomplish this object, according to the invention, functions indicative of a process of change of pattern dimension when the electron beam is irradiated on a sample are prepared in respect of the kinds of sample patterns, and dimension values of a particular pattern measured by scanning the electron beam on the particular pattern are fitted to a function prepared for the particular pattern to calculate a dimension of the particular pattern before it changes.

    Abstract: An electron gun as for a cathode ray tube includes a plurality of electrodes biased at different potentials to electrostatically shape and focus the one or more electron beams produced thereby. A dynamic focus grid is driven by a substantial ac voltage signal at the horizontal line rate, which signal is undesirably coupled through parasitic capacitance to an intermediate grid located between the dynamic focus grid and the gun anode. A resistive biasing network includes a high value resistance to divide the anode potential to develop bias potential for the intermediate grid and a capacitance to ac couple the intermediate grid to ground potential. The resistance is formed in a single layer ceramic circuit and the capacitance is formed on the single layer ceramic circuit or on the tube neck. The ceramic circuit may be located in the tube neck on or with the electron gun.
